The fly is a great option when it comes to fishing for Atlantic Salmon. The pattern is originated in the UK but will catch salmon anywhere you dip the fly in water. Great fly and not too hard to tie really. Totally worth to keep few in your box when go fishing.
This variant features a heavy 3.5mm tungsten conehead. An excellent choice when waterlevels are low and the fish wont bother with other bigger flies.
